Though Alhaitham is a character whose Artifacts needs are fairly simple, there is a lot more room for choice when it comes to his weapons. Depending on your party and your Artifacts, you can choose to prioritize Elemental Mastery or Crit stats for his sword. You can use his weapon to fill in any gaps in his stats, or boost his abilities as a Dendro DPS depending on the passive skill.
Some weapons that you can consider on your Alhaitham in Genshin Impact are:
Light of Foliar Incision
As always, a 5-star character’s best weapon is going to be whatever 5-star weapon on their banner. It’s their signature weapon for a reason. The Light of Foliar Incision is a fantastic sword for almost any DPS character because of its passive Crit Rate and Crit DMG boost. For Alhaitham in particular, the Light of Foliar Incision increases his DMG depending on his Elemental Mastery. And as a Dendro character, Alhaitham is naturally going to have a high EM. There is a time limit on the DMG boost, but you will likely use Alhaitham as part of a rotation so the cooldown on this weapon should coincide with when you take him off the field.
Mistsplitter Reforged
Like the Light of Foliar Incision, the Mistsplitter Reforged is a fantastic DPS sword. You gain separate stacks depending on: using a Normal Attack (with Elemental DMG); using an Elemental Burst; and having less than 100% Energy. Each stack increases your Elemental DMG, and Mistsplitter passively increases the user’s Elemental DMG. This plays very well with Alhaitham’s playstyle, which focuses on dealing Dendro DMG with his attacks.
Toukabou Shigure
The Toukabou Shigure was a limited sword from the Akitsu Kimodameshi event. It is an Elemental Mastery weapon that increases Alhaitham’s DMG against an enemy with the Cursed Parasol mark. This makes it a really good weapon against single enemies. On paper, the Toukabou Shigure’s passive ability does not play well with the AoE Dendro DMG from Alhaitham’s mirrors. In practice, it’s perfectly fine.
Black Sword
Black Sword is available through the Gnostic Hymn, which means you have to spend real money to get it. However, if you have it, it’s a pretty good and easily accessible sword for Alhaitham. It passively increases his Crit Rate, as well as increases his Normal and Charged Attacks. Alhaitham’s kit revolves around those, so it’s a great way to boost his damage potential.
Iron Sting
The final 4-star weapon that’s good for Alhaitham is also one that revolves around his Elemental Mastery. Its passive ability also boosts his DMG whenever he deals Elemental DMG, which is pretty much all the time. It lacks the oomph of, say, Black Sword or even the Toukabou Shigure. However, it’s more than serviceable, not to mention free. Because you can forget it, it’s easy to raise it to R5.
Genshin Impact is readily available on the PS4, PS5, Windows PC, and mobile devices.
